Operating Manual
For single cabinet installations, the Ring Network runs directly between the RCM and the Control Module.
For Remote units, the network runs additionally over data cable between the Controller and all of the backplanes in the
system.
The Ring Network is the only communication link required between the CCB and Remote Units (which have their own
backplanes, PSU and modules, but no Control Module).
